"These boots are odd but I'm keeping them! They are leather and break in upon first wearing. The toes don't cramp and arches don't fall. However, the leather on the inside of one shoe is almost a pebble grain type and the rest is smooth grain. Next, the height hits right under my calf muscle and I'm 5ft 8inches tall. The rubbing caused an abrasion. My daughter said wear socks so I am and I am keeping them. Leather!!!!"
